The invention relates to a boat davit and more especially to anchordavits for boats.

The primary object of the invention is the provision of a davit of thischaracter wherein an anchor can be conveniently operated from a seatwithin a boat in that the anchor can be moved outboard or inboardwithout liability of damage ing the boat and when inboard the saidanchor will be prevented from pounding the boat, being held Xed in anovel manner.

Another object of the invention is the provision of a davit of thischaracter wherein the necessity for the manual handling of an anchor isentirely eliminated for the placement thereof outboard or inboard and inthis way eliminating the possibility of the capsizing of the boat wherea person is required to lean over the side or an end thereof, being ineffect a safety device.

A further object of the invention is the provision of a davit of thischaracter, which is mechanical in the Working thereof and eliminatesmanual handling of an anchor` and when the anchor is within a boat itwill be properly held so that when the latter is traveling in roughwater no damage can result from impact of the anchor upon the boat andthe disposition of such anchor when held within the boat is such as toassure an even keel thereof, the davit being controlled or operated froma cable serving to raise or lower the anchor in the handling thereof.

A still further object of the invention is the provision of a davit ofthis' character, which is simple in its` construction, thoroughlyreliable and efcient in operation, convenient for mounting within a boatand automatically moves kthe anchor from within to without the boat andVice versa as Well as inexpensive to manufacture and install.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangements of parts as willbe hereinafter more fully described in detail', illustrated in theaccompanying drawings, which disclose the preferred embodiment of theinvention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a fragmentary vertical longitudinal sectional view through aboat showing the davit and anchor in association therewith constructedin accordance with the invention and in outboard position.

Figure 2 is a fragmentary top plan view.

Figure 3 is a view similar to Figure 1 showing the davit and anchorinboard.

Figure 5 is a sectional' View taken on the line 5 5 of Figure 1 lookingin the direction of the arrows.

Figure 6 is a fragmentary vertical longitudinal sectional View through agravity-acting rope or cable clamp employed with the davit.

Similar reference characters indicate 'corre` sponding parts throughoutthe several' views in the drawings. ,v

Referring to the drawings in detail, A designates generally a portion ofthe body of a boat, being conventional, while B denotes generally thedavit constructed in accordance with the invention and in associationwith an anchor C.

The davit B comprises a double-armed bracketv Il! having a closed end iland the arms of said bracket at the ends l2 thereof being fitted orformed with bearings i3 for a pivot rod M which is made fast to thesides of the boat A and being disposed crosswise at the bow end portioni5 of Y said boat for functioning as a horizontal axis for the bracketl0 which swings arcuately in a Vertical direction to assume a straddlingrelationship to the bow portion when the davit is outboard and forassuming an' inboard position as shown in Figure 3 of the drawings. Thisbracket I0 when assuming an outboard position has seating at I6, thearms of the said bracket I il being formed with bights Il for enablingcon- .Y

tact of considerable degree of the bracket at the seat lr6 and in thismanner avoiding cutting into the body of the boat'A through continueduse of the davit and in disposing the same outboard fo the dropping ofthe anchor C.

The swinging bracket Il! has journaled therein a cable wheel lor pulleyi8, being journaled at i9, and over which is trained and guided araising and lowering cable, rope or the like 2U which has coupling at 2lto the stem 2-2 of a mushroom'- shaped anchor head 23, the cable or rope2E) being of a length to extend within the boat 'A to a seat occupied bya, boatsman or attendant thereof and this cable, rope or the like 2)raises and lowers the anchor C as well as is effective for the operationof the davit B, as will be hereinafter set forth.

Extending from the bracket lli are spacerV members 24 and the ring 25create a rack forv the anchor C when its stem 22 is drawn into theFigure 4 isa fragmentary detail sectional View 55 ring or eye 25 as Willappear in Figures 1 and .3

v ing engagement with theY cable or rope 23 and avoiding slippage whenthe clamp engages with this cable or rope.

The dog 21 is formed with an elongated slot 30, which is longitudinallydisposed therein, the dog being elongated, and accommodated in this slotis a hanger pin 3l fixed crosswise in the mounting 26 so that the dog isfree in this mounting for gravity action and for displacement undermanipulation of the cable or rope 2G. The dog 21 when its foot 28 is inbiting engagementwith the cable or rope 20, the latter is held fastagainst` movement in one direction. In other words, this cable or rope20 when engaged bythe foot 23 of the dog 21 will be locked upon thewheel or pulley I8 and the latter will be held against rotation in onedirection. Thus the anchor C, when within the rack and the lockingactivity'of the dog 21 takes place upon the cable or rope 29, is heldfixe-d within the rack and will not work out of or free from thev saidrack.

The mounting 26 is provided with a notched keeper block 32, its notch 33being adapted to receive a latching toe 34 on the foot 28. This toe 34when in the notch 33 holds the dog 21 against activity or clampingengagement with the cable or rope 25 so that it can be let out or pulledupon without interference by the dog 21. The dog 21 is formed with acurved horn 35 at the heel end thereof and this horn is adapted t0 coactwith the inner face of the bow of the boat A when the davit is inboardso as to force the foot 23 of the dog 21 into clamping engage-V mentwith the cable or rope Zl and thus holding the anchor C in the rack andin a xed position within the boat.

Normally the anchor C is within the rack and the davit inboard, assumingthe position as shown in Figure 3 of the drawings. In this position theanchor C is held xed, being drawn in through the eye or ring 25supported by the members 24 on the bracket l. Now when it is desired toshift the anchor outboard, an operator or an attendant of the Vboat Apulls upon the cable or rope 20 causing the davit to swing arcuately andoutwardlyof the boat, bringing the said davit to the position as shownin Figure 1 of the drawings. The dog 21 being engaged with the cable orrope prevents the letting out of the anchor C when outboard of the boatso to release the dog 21 it is necessary to raise the cable or rope 20from the position shown by full lines in Figure 1 to the position shownby dotted lines. In this manner the dog 21 is lifted causing thelatching toe 34 to engage in the notch 33 in the keeper block 32 whencethe cable or rope 20 becomes entirely free to be let out for thedropping of the anchor C outboard of the boat. 'Ihere is no liability ofthe head 23 of the anchor C damaging the boat, either outboard orinboard, because the rack holds the anchor from making contact with theboat when the davit is moved outboard or inboard. Now when itis requiredto break anchor, the cable or rope 20 is pulled upon, drawing the anchorC into the rack and by continued pull upon the cable or rope 20, thedavit will be swung inboard of the boat A and when this davit assumesthe position as shown in Figure 3 of the drawings the horn 35 has madecontact releasing the toe 34 from the notch 33 in the keeper block 32and such dog 21 automatically clamps the cable or rope 20 fixing theanchor C within the boat, as is clearly exhibited in Figure 3 of thedrawings. Thus manual handling of the anchor for the placing thereofoutboard or inboard of the boat is entirely eliminated and when the saidanchor is inboard it can not possibly pound the boat resulting in damagethereto, particularly when traveling in rough water.

The dog 21 through gravity assumes a clamping position with relation tothe cable or rope 20 and the guide wheel or pulley I8 whenthe davit hasbeen moved outboard," the said dog 21 being released as hereinbeforesetforth while the davit is in outboard position. Now when the davit isinboard of the boat A the dog 21 is automatically operated for clampingaction thereof with relation to the cable or rope 20 and the wheel orpulley I8.

The davit hereinbefore described is at all times under the control of anattendant oroperator when within the boat A andthe anchor can be droppedfor anchoring purposes or the anchorage broken with dispatch and inconvenient manner so that manual handling or lifting of the anchor forthe placement thereof outboard or inboard is entirely dispensed with.the anchor being let out and drawn in through manipulation of the cableor rope 2lland is cast outboard or inboard automatically. l

What is claimed is: l

1. An anchor davit for boats, comprising a bracket swingable from theboat outboard and inboard thereof, a rack rigidly carriedby the bracketat right angles thereto, and having at its outer end means for engagingthe arms of an anchor, a pulley mounted on the bracket opposite therack,ra cable passing over the pulley and secured to the shank of ananchor,v an arm rigidly carried by the bracket on the opposite side fromthe rack, a pivoted cam carried by the arm and engaging the cable on thepulley, whereby the inward movement of the cable draws the arms of theanchor against the rack and the continued movement thereof swings thebracket inboard and the arm supporting the bracket and with-the anchorrigidly supported by the' rack.

Y 2. An anchor davit lfor boats, comprising a bracket swingable from theboat outboard and inboard thereof, a rack rigidly 'carried bythe bracketat right angles thereto and having at its outer end means for engagingthe arms of an anchor, a pulley mounted on the bracket opposite therack, an arm rigidly carried by the bracket on the opposite side fromthe rack, a cable secured to the shank ofthe anchor and passing over thepulley and around the rigid arm carried by the bracket when the anchoris swung inboard. and means carried by the rigid arm for engaging thecable and locking it to the pulley.
